SCDF said it was alerted to the case at at 2.50pm on Thursday (Sept
7).

SCDF dispatched two fire engines, a marine vessel, an ambulance and
officers from DART.

DART officers conducted an underwater search operation at a
depth of about 4m in low visibility.

"As there was no sign of a case, the underwater search operation
was called off at 6.30pm," said SCDF. "A periodic surface search
will be conducted henceforth," it added.

A spokesman for Sentosa Development Corporation told ST that
Sentosa's beach patrol officers responded to a request for
assistance from a member of the public at Palawan Beach at about
2.30pm on Thursday (Sept 7).

"Sentosa Rangers also alerted the Singapore Civil Defence Force and
Singapore Police Force, who have arrived onsite to render further
assistance," said the spokesman.

The Straits Times understands that eyewitnesses saw a pair of hands
waving in the water, and heard someone shouting for help.
